Faster Multiplication: Faster Multiplication
Friends! This segment will help us in fast multiplying N digit number by an another N digit number. : Friends! This segment will help us in fast multiplying N digit number by an another N digit number.
: The name of the method is VERTICAL AND CROSSWISE METHOD .
First! We will start with Multiplication of two Digit number by an another two digit number.: First! We will start with Multiplication of two Digit number by an another two digit number.
: Before going to calculation, I would like to share an Animation that will help you in multiplying a two digit by an another two digit number.
Lets take for example: Lets take for example 13 42 X
Now we will follow that animation and multiply 13 x 42. Step 1 - First multiply 3 X 2, i.e. 6.: Now we will follow that animation and multiply 13 x 42. Step 1 - First multiply 3 X 2, i.e. 6. 13 42 6
Step 2 - Multiply 1 X 2 and 3 X 4. Add the sum i.e., 2 + 12 = 14. So write down 4 with carry 1.: Step 2 - Multiply 1 X 2 and 3 X 4. Add the sum i.e., 2 + 12 = 14. So write down 4 with carry 1. 13 42 1 4 6
Step 3 - Multiply 1 X 4 = 4 and 1 we have previous carry, so the total became 5.: Step 3 - Multiply 1 X 4 = 4 and 1 we have previous carry, so the total became 5. 13 42 5 4 6
So, our final answer is 546.: So, our final answer is 546.
3 Digits X 3 Digits Multiplication: 3 Digits X 3 Digits Multiplication
Friends! First have a look on Animation of a 3 digit X 3 digit multiplication.: Friends! First have a look on Animation of a 3 digit X 3 digit multiplication.
Lets take for example: Lets take for example 253 742 X
Now we will follow that animation and multiply 253 x 742. Step 1 - First multiply 3 X 2, i.e. 6.: Now we will follow that animation and multiply 253 x 742. Step 1 - First multiply 3 X 2, i.e. 6. 253 742 6
Step 2 - Now multiply 2 X 5 and 4 X 3 and add the sum. So 10 +12 = 22. Now write down 2 with carry 2.: Step 2 - Now multiply 2 X 5 and 4 X 3 and add the sum. So 10 +12 = 22. Now write down 2 with carry 2. 253 742 2 2 6
Step 3 - Now multiply 2 X 2, 3 X 7 and 5 X 4. So, that give us 4 +21+20 = 45. Beside this, we have 2 as previous carry, so the total became 47. : Step 3 - Now multiply 2 X 2, 3 X 7 and 5 X 4. So, that give us 4 +21+20 = 45. Beside this, we have 2 as previous carry, so the total became 47. 253 742 4 7 2 6
Step 4 – Now take last two digits of the problem. Multiply 2 X 4 and 5 X 7 and add the sum up. That give us 43. And, 4 we have previous carry so total became 43 + 4 = 47. : Step 4 – Now take last two digits of the problem. Multiply 2 X 4 and 5 X 7 and add the sum up. That give us 43. And, 4 we have previous carry so total became 43 + 4 = 47. 253 742 4 7 7 2 6
Step 5 – Finally, we take the last figure of the problem. Simply multiply 2 X 7 = 14. And we have 4 as previous carry, so the total became 18.: Step 5 – Finally, we take the last figure of the problem. Simply multiply 2 X 7 = 14. And we have 4 as previous carry, so the total became 18. 253 742 18 7 7 2 6
So, our final answer is 187726.: So, our final answer is 187726.
Now friends! Similarly the figure for multiplication of 4 Digit X 4 Digit Number will be like this :-: Now friends! Similarly the figure for multiplication of 4 Digit X 4 Digit Number will be like this :-
Now you can easily drive the figure for multiplication of N Digit X N Digit number. The formula for driving the number of steps is ( 2 X N ) – 1 where N is Number of digits. : Now you can easily drive the figure for multiplication of N Digit X N Digit number. The formula for driving the number of steps is ( 2 X N ) – 1 where N is Number of digits.
